In this travelogue-style book, journalists Nathan Hodge and Sharon Weinberger chronicle their travels to nuclear facilities and historic testing sites in the U.S. and abroad in order to shed light on the current (2008) status of the world's nuclear arsenals. Interviews form the bulk of the text, mainly with current and former politicians, military personnel, and civilians associated with nuclear weapons programs and facilities. The authors describe their experiences visiting several historic nuclear testing areas, weapons complexes and the "secret cities" built in conjunction with them, and missile silos. Locations include several U.S. states as well as the Marshall Islands, Kazakhstan, Russia, and Iran. The authors' journey is in the current (2008) context of changes being implemented in response to the U.S. National Nuclear Security Administration’s (NNSA) Complex 2030 program, which is intended to modernize U.S. nuclear weapons facilities, focusing on consolidating and securing the existing nuclear facilities while also dismantling nuclear weapons. On the whole, the book offers what is not a very flattering portrayal of nuclear facilities, the people who run them, or the government agencies involved. The book’s appendix provides useful information for anyone interested in visiting the sites, including specific contact information for each facility.
